Could anyone suggest a Service center in Bangalore?

So I'm sick of all the Yamaha SVC's in my area. None of them respond properly or do the work I request them. I used to visit Highlander and Bikeone services but they're too far right now and I have a few urgent concerns that needs to be taken care of in my bike. I visited the SVC' and told them to replace a few of the things that I found was troubling and they just said they adjusted it and left it. Rest assured the concerns are back and I think they only want labour for the works and they don't want to replace the parts because then they'd have to give warranty. Does anyone know any good service centre or mechanics near Marathahalli?
